FILM DEVELOPING, FIXING, AND WASHING APPARATUS.

Specification of Letters Patent.

Patented Ju1y2,1912.

Application filedseptember 5, 1911. Serial No. 647,633.-

To of! whom it may concern:

Be it known that I, FREDERICK F. Nv, a citizen of the United States, residing at Keri-ville, in the county of'Kerr and State of Texas, have invented new and useful Improvements in Film Developing, Fixing, and lVashing Apparatus, of which the following is a specification.

This invention relates to improvements in combined film developing, fixing, and washing apparatus, more particularly of the general type disclosed in my prior U. S. Patent, No. 1,000,287, granted Aug. 8, 1911.

The structure shown in my said' patent includes a tank which incloses a flat coil upon which the film to be treated is wound; and the principal object of the present invention is to improve the manner of associating the film with the coil that this operation may be carried out more quickly and with greater convenience.

The invention also includes an improve-- ment in the device for removing the treated film from the tank, according to which the clasps by which the treated film is engaged are operated in a quick and convenient manner by a common actuating device.

The invention also includes an improvement in the coil, having in view the object of furnishing a better and more uniform support for the film.

The accompanying drawings illustrate an apparatus embodying the features of improvement referred to.

In the said drawings z Figure 1 is a plan view of the improved apparatus; Fig. 2 is a vertical sectional view thereof on the line 2--2 of Fig. 1; Fig. 3 is a detail perspective view of an element which forms. the upper bearing for the film spool; Fig. 4 is a detail sectional view showing the relation between the film and the coil; Fig. 5 is a detail sectional view showing the construction of the coil; Fig. 6 is a similar view showing aslight modification in the construction of thecoil Fig. 7 is a detail elevation of a key by means of which thefilm is wound upon the coil; Fig. 8 is a View partly in elevation and partly in section illustrating the device for removing the treated film fronr the tank; Fig. 9 is a sectional view on the line 9 9 of Fig. 8; and Fi 10 is a detail view of one of the clamps --Wl110l1 is used tosecure the film upon the coil.

Similar characters of reference designate correspondingparts throughout the several views.

- An. apparatus of the type shown in my prior patent referred to includes a tank 1, havmga lid 2; a funnel 3 at one side of said tank and preferably of Z shape;- and a vertical coil 4 within the tank and upon which thefilm to be treated is wound.

The tank 1 has at one side thereof an extension 5 which, together with an internal wall ;6, forms a casing for the film spool 7. The lower bearing for this spool comprises a raised platform 8, provided with a centering pin 9 and the upper bearing for the spool comprises a centering pin 10. The pin 10 is provided with a gooseneck extension 11, the vertical le of which has frictional engagement in a ox or sleeve 12 which is suitably located on the wall 6.

The coil 4 is provided with a suitable number of circumferentialbeads 13. Two of these beads are shown in the drawings and they may be formed as shown in Fig. 5 by stamping the metal of the coil with a projection of suitable outline; or they may be formed as shown in Fig. 6 by the provision of wires which are suitably secured to the coil. The oflice of these heads is the same paper lined non-sensitive surface 0 the film and. to space thefilm throughout as great an extent as possible from the coil. The beads 13 are, however, superior-to the projections referred to in that they afiord a more uniform support for the film and at the-same time have a smallerfilm. contacting area. The-coil is provided'with suitably arranged openings 14 through which the liquid in the tank may have circulation.

The film is wound about thecoil b means of a key 15, which is formed with a ongitudinalslot'16, and adjacent the ends of the. slot, though beyond the same, with fingers 17 which point toward-one another. The fingers 17 engage in guide channels 18, which are formed circumferentially upon the coil 4 and preferably at themean edges of overturned-extensions :19 at each end of the coil. The-outer sides of the channels 18 tered by the pin 9 an thereupon the "pin 1Q is fittedinto the spool, the'legof the-extension 11 of said pin beingfitted in the box' or sleeve 12 and having sufiici'ent frictional engagement-gin saidbox or sleeve to avoid' be com ng displaced. The black paper of the film roll is threaded through the slotlG and the. key is then given one or two turns to secure the paper which has heen threaded through said key. Thereafter, the films and the -hlack paper are connected by the gumnied stickerwithiwhich the film is provided near where the word Stop occurs.

. In performing this operation the lower 'end of the key is centered in a socket which issuitably located upon the base of the tank and which is provided with a slot 21,

so arranged that the key may be withdrawn laterally from the socket a direction to end of the black-paper linin by being given;

"18 winding the film upon the coil care must be taken that the black paper lining adjoins the beadslB in order that the sensitwo side of the film may be fullyex'posed to '.the act-ion of'the'liquid in the tank. After the film has been completely wound upo'nthecoil and the fingers 17 have passed from the channels 18, the key is disengaged from the a sufficient number of turns or this purpose,

- and the film is, thereupon secured at the ends ofthe coil by means of the clamps-22, 'oneof which is shown in Fig; 10, and: which are similar in all respects to the clamps 11 shown, in -my patent referred to.

' After the 'film has been wound upon the coil, the lid 2 is applied and the operations of developing, fixing, and washing are carr'ied out in the manner explained in my patcludes a pair of parallel upper and'lower" lentreferred to.-' When these operations are completed, t-he'film. is removed bythe device.

shown in Figs. 8 and; 9. This device in-,

bars 23 and 24, the lengthof which corre \sponds to a diameter of thetank. .The bar 24 has at its ends upstanding goosenecks 25- and together with'thebar 23 supports a plurality of-clasps 26,- the numberof which corresponds. to the number of convolutions.

of the coil alon a diameter of the tank.

Each. clasp 26 includes a spring-pressed finger 127, the upper end of which terminates at a point between the bars 23 and 24; and

the said upper, ends of the fingers 27' are connected to wires; 28 ofwhich there'arej two; The inner ends at suitably connected to studs -which project a laterally from apost 29. 'Thelatter' is 'curnaled in the bars 23 and 24 and has at.

its upper end a suitable finger piece.

the ,wires- 28 are menses After the film has been completely treatedthe lid ls'removed'froin the tank and the film removing device is operated, the goosenecks 2510]? said device being passed over the upper edge of the a tank at oppos te po nts thereofandthe post 29 beingt-urnedsO as to efiegt the simultaneous opening of the Clasps 26.. v Thefihn removing device is then lowered with its 'clasps open until about an eighth of an inch of the upper edge portion of the film has passed between=the members of said clasps' Thereupon the post 29' is re leasedand' the springs with which the clasps are provided close the fingers 27 upon the film. The clamps 22 are then removedand the fiLn is lifted from the tank.

' The construction shown inflm prior pat- 'ent is not ad'aptedior dayligh loading,"it

beinghecessary topetformthis operation in the dark room. Withthe present'eonstruction, however, the lda'dingmay be car ried out either in the dark-room or in day-'- light, according to the choice -oi'the user, and dependingon the materials employed; 1

lfdaylight loading is desired the spool is removed from the lied lk and the superfiuone part of the backing paper is torn away.- a

to' within two or three inches of the word Stop, or at the point where the gummed sticker is'located. The film is thenconnect' ed to the backing paper by 11162.118 of this sticker and the end of the paper is trimmed in order that it may be readily threaded through theslot l6. The films/pool is then fitted into the tank in the manner explained and thekey 15 isengaged with-the channels, 18. Before unwinding the film from the spool, the developer shouldv be pouredinto i the tank as quickly as possible, and to a level about an inch. or three quarters'of an inch at least, above the top ot the spool, For this operation the developer should have been previously made. non-actin'ic" by the use of any of the well known-prepara-' tions for this purpose, care of course being taken asto the selection of strengthan'd, proportion with regard to the workat hand.' After thedeveloper has been added lathe? manner explained, the film, is wound upon the. coil and secured by the clamps 22, the lid isapplied to the tank andthe several steps, 7

of treatmentare carried out,

,The'several parts of the apparatus are f j where practical, constructed of copper and are heavily nickel plated, in order that deteriora'tibnof the metal by thesolutions brought into contact therewith during the several operationsmay be prevented. 'Having fully describ claim: v
